Larry Mize shot an 8-under-par 64 on Thursday to take a one stroke lead after one round of the Senior Players Championship at Caves Valley Golf Club in Baltimore.

Mize, the 1987 Masters champion, had nine birdies and one bogey while shooting his lowest round of the year and the second lowest of his Seniors career. He was particularly effective on the green. He had just 22 total putts on the round and that included 12 one-putts.

“Obviously to shoot 64 you always have to get the putter going, and the putter was working really well today,” Mize told PGATour.com. “I made a (50-foot) bomb on No. 9 that if you would have told me I could two-putt, I’d have picked up my ball and not putted it. Things just went well for me today.”
